Help Paywall Integration IDK how to check if cancelled

I don’t know how to check what happens if someone cancels their subscription I want them to go back to the MainOnboardingView. Your help would be highly appreciated. Here is the file where I make the check on what view to show. It is the main App file:
import SwiftUI
import SuperwallKit

Imagine “@” where it is supposed to be forum wouldn’t let me post the code otherwise

main
struct GospelApp: App {
StateObject private var prayerStreak = PrayerStreak()
StateObject private var notificationsManager = NotificationsManager.shared
AppStorage(“isFirstLaunch”) private var isFirstLaunch: Bool = true
AppStorage(“hasScheduledTestimonials”) private var hasScheduledTestimonials: Bool = false
Environment(.scenePhase) private var scenePhase
AppStorage(“isPremium”) var isPremium: Bool = false

init() {
    Superwall.configure(apiKey: "[Redacted]")
}

var body: some Scene {
    WindowGroup {
        Group {
            if isPremium {
                MainTabView()
            } else {
                MainOnboardingView()
            }
        }
        .environmentObject(prayerStreak)
        .environmentObject(notificationsManager)
        .onAppear {
            if isFirstLaunch {
                // Request notification permissions on first launch
                notificationsManager.requestPermission { granted in
                    print("Notification permission granted: \(granted)")
                    
                    // If user denies permissions, we won't be able to schedule the welcome notification
                    // in the requestPermission callback, so try again here
                    if granted && notificationsManager.notificationsEnabled {
                        notificationsManager.scheduleWelcomeNotification()
                    }
                }
                isFirstLaunch = false
            } else {
                // Check if we're in the second week and should schedule testimonial notifications
                checkAndScheduleTestimonials()
            }
        }
        .onChange(of: scenePhase) { oldPhase, newPhase in
            if newPhase == .active {
                // Reset the badge count when the app becomes active
                notificationsManager.resetBadgeCount()
                
                // Check notification authorization status
                notificationsManager.checkAuthorizationStatus()
                
                // Check if we're in the second week and should schedule testimonial notifications
                checkAndScheduleTestimonials()
            }
        }
    }
}

private func checkAndScheduleTestimonials() {
    // First check if notifications are authorized and enabled
    if !notificationsManager.isAuthorized || !notificationsManager.notificationsEnabled {
        return
    }
    
    // If we haven't tried to schedule testimonials yet, check if we should
    if !hasScheduledTestimonials {
        // Let the NotificationsManager handle the logic of whether we're in the second week
        notificationsManager.schedulePersonalNotifications()
        hasScheduledTestimonials = true
    }
}
